生物学     用語集 (例 epibenthic)

Mainly found in deep reef channels and seamounts, in current prone areas (Ref. 48635). Juveniles may be found in tide pools (Ref. 5222). Feeds on reef fishes, skates, crabs, and spiny lobsters (Ref. 5222). Considered to be exceedingly territorial and very aggressive towards intruders. Vulnerable to spear fishers (Ref. 5222). Hand fed by divers in certain areas, but potentially dangerous to the inexperienced. In the Hong Kong live fish markets (Ref. 27253). Solitary (Ref 90102).
